SPECIFICATION forming part of Letters Patent No. 261,621, dated July 25,1882.

Application filed January 23, 1882. (No model.) 7

To all whom it may concern: I

Be it known that I, SAMUEL J. MoDoWELL, of Boston, of the county ofSuffolk and State of Massachusetts, have invented a certain new anduseful Improvement in Camp-Stoves, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, which make part of this specification, and in which- Figure 1represents a view in perspective of my improved oven, with one of thecovering, sections removed. Fig. 2, a vertical longitudinal sectionthrough the same at the line ac xof Fig.1; and Fig. 3, aview inperspective of the fire-box and outer casing of the oven, with a portionof the front side broken away to show the interior.

It is'the object of my invention to render the oven portable by soconstructing its parts that they may be packed in a small compass fortransportation, and readily and securely united where required for use,when the oven is surrounded on all sides and at the top and bottom witha continuous flue, having also a provision for equalizing the heat atall parts within the oven; and to this end my invention consists, first,in the combination of the sectional oven provided with an opening andflange, as hereinafter described, with the sectional outer case and aseparate sleeve adapted to such case and flange; second, in thecombination of the outer casing and oven, constructed in sections andarranged and provided with a flange and sleeve, as described, with oneor more shallow pans arranged in the oven and upon its bottom andcharged or to be charged with sand, all being as hereinafterspecificallyexplained.

To enable others skilled in the art to make and use my invention, 1 willproceed to describe its construction and operation.

The outer casing of my oven is composed of metal sheets, made in anydesired number of sections. In the drawings the side pieces arecontinuous and have flanges a a a a turned inward at each corner, towhich hooks 1 1 are securely attached, while the front plate, B, and therear plate, 0, are of equal length and made plain at their ends to restwithin the flanges and complete a square form. The front and rear platescarry staples 2 2 at their corners, to receive the hooks 1 l, and thefront, rear, and

side plates carry a suflicient number of books,

3 3 3, to fasten them securely to the bottom plates, which carry thestaples 4 4 4 in or on the continuous flange,forall the bottom plates, 5D D, are flanged on their outer edges, and these flanges hold the sidesand ends in a vertical position, and when the top sectional plates, E,are also flanged and placed in position and securely fastened by hooksand staples or oth- 6o er fastenings, the whole forms the complete outercasing, to receive the oven, sustain the fire-box and chimney, and allowa free fluespace all around the oven. The fire-box F is placed in thecenter, or nearly so, of the bottom plates of the oven, and is heldsecurely there by its flanges 5 5, which are turned all around its topor upper edge. The fire-box may be simply perforated at the bottom topermit the escape of the ashes, or it may carry grate-bars, and it maybe plain or corrugated on its sides and use refractory lining material,

if desired. A door on one side of its sides permits the introduction ofthe fuel, and a register in the door may be made to regulate the draft.

The oven G, like the outer case, is made of any suitable sheet metal,and in sections, 6 6 6, in Fig. 2, and these sections are securelyfastened together whenit is desired to use the oven in the same manneras described for fastening the plates of the outer case. The oven has anopening, 7, in front, surrounded by a sleeve,

8, that is received in a flange, 9, that is fastened to the front plate,B, which also contains 8 5 a door, 10, to give access to the interior ofthe oven.

When the sectional plates that constitute the oven are placed within thecase and supported by stools or trestles 11 at its corners 0 the sleeve8 is pushed into the flange 9 until the flue-space between the oven andcase is equal on all sides. The top sections now can be placed inposition, fastened together and to the side and end plates, and when thepipeor 5 chimney 12 is placed in its position on the center of the topplate the oven is ready for use,

and may be set on feet 0 0 0 in any desired spot on the instant, orsimply by resting two rods or bars of iron on wooden forks a proper modistance apart, and so arranged as to give the outer case a secure andhorizontal support.

To prevent the direct action of the flame and heat from the fire-potfrom heating the bottom plates of the oven too rapidly, I cover thewhole bottom of the oven with sectional metal pans 13 13, and fill thesewith sand or any refractory material, and thus prevent the rapid burningof the bottom plates and distribute the heat of the oven so as to nearlyequalize the temperature within when in use.

It is obvious that such ovens may be made of any desired capacity, andthat they are, as experience has proved, of great importance to themilitary service, for alter a baking for a regiment has been finished inthe morning the sections of the case and oven can be separated in a fewmoments and packed in a small space, loaded, and transported, so as tokeep up with the troops, and readily be replaced to bake for theirsupper.

What I claim as my invention, and desire 20 to secure by Letters Patent,is-

1. The combination of the sectional oven G, provided with the openings 7and flange8, With the sectional oven-case and the separate sleeve 9,adapted to such case and flange, all being arranged and constructedsubstantially as set forth.

2. The combination of the outer casing and oven constructed in sections,and arranged and provided with the flange 8 and sleeve 9, as described,with one or more shallow pans, 13, arranged in the oven and upon itsbottom and charged or to be charged with sand, as explained.
